A power cable or extension lead carrying high current heats up.

The power stated for a heater applies at its rated voltage.

Check manual valve ON / OFF first, then set AUTOMATIC OPERATION and verify valve settings.

Compare the reading with another known-good probe or a reliable thermometer.

If two heaters are to heat one process controlled by one controller, both should be switched and regulated together through the controller output.

If the temperature displayed by the controller is clearly unrealistic, there is no reading, 0°C appears, or a constant value of 85°C is shown, first check the probe and its connection.

No heating does not always mean that the output is faulty.

Motors, contactors, solenoid valves, large heaters, relays, variable-frequency drives and long cables can introduce interference into the installation.

Many controllers and automation modules operate on the 2.4 GHz Wi-Fi band.

The controller local web page is available only when the phone or computer is connected to the appropriate network.

Overheating does not always mean a controller failure.

Pinout of D-SUB 9 and RJ45 connectors used for sensors and inputs. Numbering is shown from the socket side.

Switching the heater off or reducing its power does not stop the temperature from rising immediately.

A working local web page means that the controller communicates with the phone or computer over the local network.

A fan motor needs sufficient starting torque.

Calibration is used to correct a small, repeatable difference between a correctly operating probe and a reliable reference.

How to position a temperature probe correctly in a smoker and a distillation system so the controller receives a representative measurement.

Every real heating system has thermal inertia.

The upper temperature alarm indicates that the temperature has exceeded the set threshold.
